How to Convert Horizontal Video into Vertical Video for YouTube shorts

Hello Friends! I hope you are doing well, May God peace be upon you.

if a video was recorded vertically from a smartphone, then it can be played back as horizontally, but with the picture turned on its side. In general, modern phones put a special checkmark when saving a video, which the player reads and orientates the video correctly. Your video may not display correctly if:

  • Some older versions of players cannot read the orientation parameter in space;
  • The smartphone does not save the orientation parameter.

At the same time, on one computer everything will be played as it should, while the other person’s video will be flipped horizontally. There are two options for solving the problem: rotate the video in the player or make the horizontal video vertical forever. In this article, we will deal with the second method.

Fast and easy way to flip videos:

You will need Windows 10 and the built-in Photos app. In the search bar of the “Start” menu, write “photos”, launch the application and go to the “Video Editor” tab. However, this program may not be available in various builds of Windows 10. Then we write in the start menu “store” and launch the application store “Microsoft Store”. In the search, we write “Photos”, and install and launch the application:

To convert the video to vertically oriented from a horizontal lying position, click on the plus sign “New video project” and give the project any name:

Next, you need to drag the file with the mouse to the program window in the “Project Library”, and then drag the already-added video again to the bottom of the window. Now everything is ready for flipping, press the button with the image of a circular arrow, it rotates the video clockwise:

Click the “End Video” button :

The program has practically no settings for the output format, just select the preferred quality, I recommend “High 1080p”, even if the original is in 720p resolution. the inverted video should be larger vertically.

Click the “Export” button and save the file. Windows 10’s built-in video editor has many significant drawbacks:

There are no codec settings for the video, which makes the new video huge. For example, a 50 MB inverted video clip. It began to occupy 250 MB, which is 5 times more. For small videos up to 1 minute, this is unimportant;

  • For the same reason, it is impossible to save a video in formats other than “.mp4”, for example, mkv or avi;
  • The resolution of the vertical video remains horizontal; in fact, the video is simply framed with black stripes on the sides;
  • Works on Windows 10 only.

By Video Processing:

To work without restrictions, we will use third-party software. The video master program can apply the most popular effects to videos:

  • make a vertical video from a horizontal video;
  • make a horizontal video from a vertical video;
  • trim, cut out the excess, divide into parts, and combine without conversion;
  • apply effects, text, graphics, crop;
  • change video speed, replace sound, etc.

The program is free, but some functions require the purchase of a license. The interface is intuitive because the emphasis is on simplicity and convenience so that the user does not waste hours reading the instructions.

First, you need to add a video file by dragging it with the mouse from the explorer to the program window or using the “Add” button from the main window. Next, click the button as in the screenshot, or select “Processing -> Rotate Video” in the menu, and select how many degrees you need to rotate:

  • 90 degrees: clockwise
  • 180 degrees: flip upside down
  • 270 degrees: counterclockwise

In the viewport, you can see what happened in the end. Now you need to properly save the video with maximum quality preservation. Unlike the operations of splitting and joining clips, it is impossible to convert the video to vertical without conversion. This means that you need to choose the format and codec for the new video. Click on the arrow to select the codec:

For files with a resolution of 1280 × 720 and 1920 × 1080 (FullHD), I recommend choosing codecs marked “HD” :

  • 264: the output will be a “.mp4” file compressed with the H.264 codec. High video quality with minimal file size;
  • MKV: differs only in the file extension “.mkv” ;
  • MPEG4: “.mp4” file, larger size, worse quality, but better compatibility with old consumer players;
  • XviD, DivX, AVI: do not use for HD resolutions, it is intended for compressing DVD formats, but it will have maximum compatibility with old players;
  • 265: Latest HEVC Codec, Highest Quality, Smaller File Size, Maximum Processing Time, Minimum Home Appliance Compatibility.

By clicking the “Parameters” button, you can change the codec and sound encoding parameters:

By default, the maximum sound quality is selected. Optionally, you can reduce the bitrate to 96 Kbps if the original quality is at the same level. The rest is not interesting, except for the tab with a breakdown by device type. You can see what codecs the original video stream was encoded with by going to the “Processing -> File Information” menu.

The screenshot shows that my video was encoded with the H.264 codec with a bitrate of 8008 Kbps, with a frame size of 1280 × 720; audio was encoded with AAC codec with 97 kbps bitrate. Accordingly, you can set approximately the same parameters to get the same video quality at the output. Click on the item “Excellent quality” :

I need to adjust the video resolution. Considering that the original picture size is 1280 × 720, I decrease the slider to 720 × 1280 (on the contrary, since the video has become vertical). The default maximum quality allowed us to set about 3000 Kbps, less than in the original. I am sure that more is not needed, in my case. But if you need a higher bitrate, then we increase the file size by megabytes.

If the bitrate is too low, the picture will consist of squares and various artifacts will appear, and the file size will be greatly reduced. If you need to get a small file, then along with the bitrate you need to reduce the resolution, for example, to 576 × 704.

Specify the folder for saving and press the “Convert” button. The save process will take about the same length as your video. The exact time, of course, depends on the quality of the video and the power of the computer and may differ several times. For too-long video clips, you can go to the menu “File -> Convert and turn off the PC”, then the computer will shut down, at the end of the saving process.

I hope you have Learned Something from here.
